Yeah no problem, PM me your phone number.
Im working in london till thursday evening then will be driving back home to taunton, and was planning on taking the mrs RS2'd 172 out to finish running the engine in when I got back (only built it last weekend), so I will just do so driving to your place rather than driving around randomly like I was going to be doing.
Like I said though, if your TB is knackered, I dont have a spare one so you will need to get one. If you have it by thursday I will fit it for you then (its very easy though I can show you what to do if you havent got one by then)
